Describe the Bug

I found an incredibly important bug. My directory structure is like this: content\posts.

So I set it up this way in config/menu:

[main]]
name = "Blog"
pageRef = "posts"
weight = 10

I can see that a blog menu has been added to the homepage, and clicking on it allows me to see all the .md files in the posts folder.

However, when I set it up like this in params.toml: mainSections = ["posts"], no articles are visible on the homepage.

I've checked all possible options and can't resolve the issue, and after carefully reading the documentation, I found that my settings seem correct.
The documentation states: The articles listed in this section are derived from the mainSections setting, which allows for whatever content types you are using on your website. For instance, if you had content sections for posts and projects, you could set this setting to ["posts", "projects"].

But even so, the recent articles still won't display.
Later, I looked at the options of other Hugo themes and suddenly thought of a possibility.

I made the following change: mainSections = ["post"]. After restarting the server, the recent articles immediately became visible.

To Reproduce

just follow the above

Expected Behaviour

post or posts? Why is it correct to use "Posts" in the menu, but I must use "post" in the mainsection?
